The universe is not testing you, in fact its giving you what you want. You wanted your ex, and now you are finally in a place where that resistance is fading. In your case you don’t want him anymore. So at this fades, the manifestation becomes easier to come into your experience.
I hear my ex’s first and last name on a daily basis, and more when im relaxed about it. I don’t really pay attention to it, but it tells me my vibration is clearing up from the negative vibes I was sending before.
